Case Type   : 多节点写入
Case Name   : 备机执行定义数据类型转换的DDL语句
Create At   : 2023/07/17
Owner       : opentestcase033
Description :
    1.修改enable_remote_execute参数值为on
    2.自定义类型转换函数
    3.备机创建显式转换关系
    4.备机调用创建成功的转换关系
    5.备机删除自定义类型转换
    6.查看日志打印
    7.清理环境
Expect      :
    1.修改成功
    2.成功
    3.创建转换关系成功
    4.源类型转化为目标类型，7322
    5.成功
    6.记录DDL语句转发到主机执行
    7.成功
